Hi,
I need opinions on what should I do...
I've did some searching on the forum about this, and it states that most of the prob comes from faulty Throttle Body Positioning Sensor. Well I started with unplugging the batteries n taking off my TB. I cleaned my butterfly valve, intake runners, my intake manifolds, MAF sensors, and stainless steal filter. After all of this I still had the VSC on/off light coming on.

I decided to take it to the local Stealership(Lexus of Murray in SLC, Utah). They called me and stated the lights was on because "000989 NEEDS MASTER CYL" Price was to fix is $2000
Plus they charged me $110 diagnostic fee


Thanks.

 

Ouch, I would say your bet would be to ask in the regional section of this site for a tech that works for lexus. Go to OELexusparts.com and see how much they charge you. if not then linger around the Stealership and ask one of the techs there. I did that with my old mazda and got a great deal. Good luck though.

 

Thanks for the response.

I checked out Ebay and they had a slightly used set from a sc430 for a quarter the price quoted by the dealership. Id probably install it myself.
